U-Type Double Girder Gantry Crane Cap. 10T-50/10T

Product Description:

Profile

Double beam hanger gantry crane is suitable for general loading/unloading and lifting/handling operations in open-air warehouses or railways.

It is composed of beam, support legs, crane travelling mechanism, trolley, electric equipment and so on. The strong legs shape is like a English Letter U, this design is very benefit when the container pass by thought the legs. The control mode could be ground control, remote control, cabin control.

The bridge adopts box welded structure, and the cart running gear of the cart using driven separately. All the mechanism operation operated indoor. The conductive type of crane is divided into two kinds: cable and sliding wire. This crane is suitable for the temperature of -25 ℃ —+40 ℃, the humidity is less than 85%, and it should work in the place without fire, explosion and corrosivity, also prohibit to lift of toxic, flammable and explosive materials. The product is compact in structure and reliable in operation，it is an advantageous tool for improving working conditions and improving labor production.
